How to Check Ignition Coil on Lawn Mower
Lawn mowers are essential gardening tools that help maintain the beauty of your lawn. However, like any mechanical device, lawn mowers can experience issues, and one of the most common problems is an ignition coil failure. The ignition coil is responsible for creating the spark that ignites the fuel-air mixture in the engine, and if it’s not working correctly, your lawn mower may not start or run smoothly. In this article, we will guide you through the process of how to check the ignition coil on your lawn mower.
Identifying the Ignition Coil
The first step in checking the ignition coil is to locate it on your lawn mower. The ignition coil is typically located near the engine, and it may be attached to the engine with bolts or screws. Look for a coil-shaped component with two wires connected to it. This is the ignition coil.
Checking the Ignition Coil with a Multimeter
Once you have identified the ignition coil, you will need a multimeter to test it. A multimeter is a versatile tool that can measure voltage, current, and resistance. Here’s how to use a multimeter to check the ignition coil:
1. Set your multimeter to the ohms (Ω) setting.
2. Disconnect the two wires connected to the ignition coil.
3. Touch the multimeter probes to the two wire terminals on the ignition coil.
4. If the multimeter displays a reading between 0.5 to 10 ohms, the ignition coil is likely in good condition.
5. If the multimeter displays an open circuit (OL) or a reading that is too low or too high, the ignition coil may be faulty and needs to be replaced.
Checking the Spark Plug
After testing the ignition coil, it’s essential to check the spark plug as well. A faulty spark plug can also cause starting issues in your lawn mower. Here’s how to check the spark plug:
1. Remove the spark plug from the engine.
2. Inspect the spark plug for signs of wear, such as a glazed porcelain or a buildup of carbon.
3. If the spark plug looks worn or damaged, replace it with a new one.
Conclusion
Checking the ignition coil on your lawn mower is a relatively simple process that can help you identify and resolve starting issues. By following the steps outlined in this article, you can save time and money by diagnosing and fixing the problem yourself. Remember to use the proper safety precautions and tools when working on your lawn mower, and always refer to the manufacturer’s manual for specific instructions related to your model.
